The Open Identity Gateway (OpenIG) is a high-performance reverse proxy server with specialized session management and credential replay functionality.

OpenIG is an independent policy enforcement point that reduces the proliferation of passwords and ensures consistent, secure access across multiple web apps and APIs. OpenIG can leverage any standards-compliant identity provider to integrate into your current architecture. Single sign-on and sign-off improves the user experience and will vastly improve adoption rates and consumption of services provided.

  • Extend SSO to any Application
  • Federate Enabling Applications
  • Implement Standards Based Policy Enforcement

How it Works

OpenIG is essentially a Java-based reverse proxy which runs as a web application. All HTTP traffic to each protected application is routed through OpenIG, enabling close inspection, transformation and filtering of each request. You can create new filters and handlers to modify the HTTP requests on their way through OpenIG, providing the ability to recognize login pages, submit login forms, transform or filter content, and even function as a Federation endpoint for the application. All these features are possible without making any changes to the application's deployment container or the application itself.

OpenIG works together with OpenAM to integrate Web applications without the need to modify the target application or the container that it runs in.

  • Support for identity standards (OAuth 2.0, OpenID Connect, SAML 2.0)
  • Application and API gateway concept
  • Prepackaged SAML 2.0-based federation
  • Password capture and replay
  • Works with any identity provider, including OpenAM
  • Single Sign-On and Single Log-Out
  • 100% open source

How-to build

For windows use:

git config --system core.longpaths true
git clone --recursive
mvn -DskipTests -Dmaven.javadoc.skip=true install -f OpenIG
mvn install -f OpenIG

How-to run after build

mvn -f OpenIG/openig-war jetty:run


mvn -f OpenIG/openig-war tomcat7:run-war
